嘉定白蒜在国际市场享有一定声誉,每年为国家换取不少外汇,是我县农业生产中一项重要的经济收入。大蒜一般在9月下旬排种,5月20日前后收获,全生育期230天左右。一生共长10～11张叶片,2月底到3月初为7叶期,此时进入蒜瓣分化阶段,4月20日左右,蒜瓣长到谷粒大小。从4月20日～5月20日是大蒜生长后期,这时大蒜还保持6～6.5张功能叶片,蒜瓣依靠这些叶片所制造的养份迅速膨大。1979年,我们在华亭邵家生产队,做了剪除后期功能叶对蒜头重量影响的试验,各处理取样100株大蒜,茎粗相仿,绿叶数6.5张,于4月21日
Jiading white garlic enjoy a certain reputation in the international market, exchange a lot of foreign exchange for the country each year, is an important economic income in our county agricultural production. Garlic is generally planted in late September, around May 20 harvest, the whole growth period of about 230 days. A total length of 10 to 11 leaves, the end of February to early March 7 leaf stage, this time into the cloisonne differentiation stage, April 20 or so, the garlic grows to the grain size. From April 20 to May 20 is the late garlic growth, then garlic still maintain 6 to 6.5 functional leaves, garlic leaves rely on the rapid expansion of the nutrients produced by these leaves. In 1979, we produced the team at the Huating Shao Sha production team and did the experiment of cutting off the influence of the functional leaves on the weight of the garlic head. Each sample of 100 garlics was sampled and the stem diameter was similar and the number of green leaves was 6.5. On April 21
